Q:What are the types of steel refractory materials
(1) clay refractory brick (2) high alumina refractory brick
Q:Could you tell me how does fire protection standard of decorative material is divided?
Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.
Q:Who knows the fire endurance of B-level fireproof doors and windows?
According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.
Q:For refractory, what is critical particle size? Thank you.
Critical granularity means the maximum size of particles in refractory.
Q:Do you know where I can buy refractories?
A Address of Guangzhou Lingnan Refractories Co., Ltd. : No.1069 Guanghua 1st Road B Address of Guangzhou Aolian Refractories Co., Ltd. :
Q:Which fireproofing materials factory is the best in Xiangyang?
Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
Q:I wanna ask about the building insulation materials fire rating?
In China, the main external insulation materials are divided into level A, level B1, level B2 and level B3. According to the current "Combustion Performance Classification Method of Building Materials", level A thermal insulation material is incombustible material and inorganic insulation material. However, there are few level A thermal insulation material on the current market, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the organic insulation materials are popular in the market. Level B insulation material can be divided into three levels, level B1 is flame-retardant, level B2 is flammable, and level B3 is flammable. Level B1 nonflammable thermal insulation material is determined by the fire endurance of the material, in addition, different parts of material is divided differently! More common is EPS / XPS insulation boards which have added flame retardant through special treatment. B2 level of combustible insulation materials, common to EPS expanded polystyrene foam insulation board and XPS board, that is, we often say that the general board. The ignition point of this material is very low, and it will release a large amounts of harmful gases in the combustion process. level B3 flammable insulation material is a kind of thermal insulation material which mainly made of polyphenyl foamed. Since this material is highly flammable, it has been eliminated. Civil construction insulation materials, popular building insulation materials in China's current market are mainly made by three organic foam, such as EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane)
Q:About the market issues of thermal insulation material and refractory material.
In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu
Q:The difference between refractory and thermal insulation material
In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
Q:What are the specifications of fire resistant bag?
Fire resistant bag is featured by wear resistance, resistance to heat, shock, acid and alkali, somke, fire, bacteria, mould and static electricity. Fire resistant bag is generally used for table top, desktop, wall face, cabinet, office furniture, wall-hung cupboard, etc. The common specifications include: 2135mm×915mm, 2440mm×915mm, 2440mm×1220mm, thickness 0.6-1.2mm. I hope it can help you.
